A gender-transitioning triple-killer's risk of reoffending may be exacerbated by a requirement to advise authorities of any significant changes to her appearance, a court has been told.
Regina Kaye Arthurell is fighting the length and extent of a three-year supervision regime sought by the government, following the expiration of the elderly offender's 24-year jail term in May.
A proposed condition of the government's proposed extended supervision order would require Arthurell to inform authorities of "any significant change" in her appearance.
"I thought that might prove quite onerous, given it's an intrinsic part of her transition," forensic psychiatrist Yolisha Singh told the NSW Supreme Court on Monday.
Dr Singh said a person undergoing transitioning would usually take classes in elocution and deportment, changing the way they speak, walk and hold themselves.
A condition on appearance - a regular sight in extended supervision orders - could be perceived by Arthurell as "punitive" and such perceptions could exacerbate the offender's risk of reoffending, Dr Singh said.
Dr Singh and forensic psychologist Ivanka Manoski each rated the septuagenarian's reoffending risk as moderate, identifying interpersonal conflict and a return to alcohol use as specific risks.
Both said state supervision of Arthurell for two years would be adequate for her to establish therapeutic relationships with a psychologist and other service providers.
The government wants a three-year order.
"She is likely to have been institutionalised, given she has spent 24 years in custody so she will need a lot of support in the community," Ms Manoski said.
Arthurell was paroled in November with six months remaining on her 24-year sentence for bludgeoning Venet Mulhall to death with a piece of wood in 1995.
At the time of the murder in Ms Mulhall's Coonabarabran home in central NSW, the killer was on parole - having unlawfully killed naval officer Ross Browning in the Northern Territory in November 1981 and his stepfather Thomas Thornton in Sydney in May 1974.
All offences were committed under her birth name Reginald Kenneth Arthurell before she came out as transgender in custody.
Ms Mulhall's brother Paul Quinn has repeatedly raised fears Arthurell could kill again.
The hearing continues.
